Ways of Knowing Science: ILS 153 Name:______________________________ Climate Change homework 1: The Atmosphere To understand the issues with climate change, it is necessary to understand the dimensions of our atmosphere and the influence of human on it. To do that, you are going to do two scale models of the planet and calculate your carbon footprint. Here is the information you need: Distance from center of Earth Sea Level 6,371 km Mt Everest 6,380 km Top of Troposphere 6,382 km (Troposphere average is 11 km thick) Top of Stratosphere 6,421 km (Stratosphere average is 40 km thick) Top of Mesosphere 6,461 km (Mesosphere average is ~50 km thick) Top of Thermosphere 6,871 km (Thermosphere average is ~500 km thick) Question #1: Make a scale model of the Earth on a sheet of paper. SHOW YOUR WORK SO THAT I CAN FOLLOW IT. Put on sea level, the top of the mesosphere, and the top of the thermosphere. Calculate how thick the troposphere would be, but you will not be able to put it on the model because it is too small (This is the point: Human existence is completely dependent on the troposphere) Question #2: Make a scale model of all of the layers of the atmosphere above Wisconsin on a sheet of paper. Denote the correct scaled height of Mt Everest. Assume that the surface of the world is flat. SHOW YOUR WORK SO THAT I CAN FOLLOW IT. As a reminder from Homework #1: Distance on map Scale (known) = _______________ Distance in reality (known) which is exactly equal to… Distance in map = Scale (known) * Distance in reality (known) Question #3: Using either of the following websites, calculate your carbon footprint. <http://www.climatecrisis.net/takeaction/carboncalculator/> <http://www.begreennow.com/calculator> (For students who do live in dorms) Report the numbers in the space below. What is the cause of your single largest carbon output?
